Abstract

Data is transmitted via a radio interface in a radio communications system in that at least one subscriber signal is transmitted, which has an individual fine structure applied to it and, in addition to data symbols in data sections, contains a midamble with known symbols. The fine structures of the data sections and of the midamble differ. At the transmission end, a sum signal is produced which contains signal sections to which different fine structures are applied. The sum signal is filtered in at least one transmission filter and is transmitted via a transmission channel to a receiving radio station. A control device controls the addition so that different attenuation of the signal sections is compensated for by the filtering. The method is suitable, in particular, for mobile stations having a single or variable data rate, and for base stations for use in 3rd generation TD/CDMA mobile radio networks.
